Metals in the aquatic environments are an environmental concern. The extent of the negative impact of metals is strongly dependent on the molecular form of the metal. Metals may be bound to natural organic matter, bacterial and/or mineral surfaces. Often (but not always), the bound metal is less toxic and possibly less mobile then the free form. Analytical methods that determine forms of metal are termed speciation methods. Metal speciation in aquatic systems is my primary research interest.
